The thromboxanes are also formed by degradation of prostaglandin endoperoxides (see Fig. 11 Thromboxanes are synthesized in platelets and act to lower platelet cAMP formation, which then leads to aggregation of the platelets and their deposition on the vascular endothelium.

Postaglandins & their related compounds prostacyclins (PGI), thromboxanes (TXA), leukotrienes (LT) & lipoxins are collectively known as eicosaniods, they all contain 20C. Structure of prostaglandins: Prostaglandins are derivatives of carbon fatty acid - prostanoic acid, hence known as prostanoids.

prostaglandins are a group of biologically active compounds with a plethora of different actions and produced in virtually all tissues of the body.

Unlike most autacoids (substances formed by cells themselves, which act as ‘messengers’ to other cells) they are not synthesized and stored ready for use.

Rather, they are produced on demand in response to a great variety of stimuli.Prostaglandins were first discovered and isolated from human semen in the s by Ulf von Euler of Sweden.

Thinking they had come from the prostate gland, he named them prostaglandins. It has since been determined that they exist and are synthesized in virtually every cell of the body. New style prostaglandins 1. Therapeutic uses of Prostaglandins Dr.
